如果你读过我的其他问题 ，你就会知道我花了本周末6502 CPU仿真器放在一起作为编程练习。
该CPU仿真器已经基本完成，似乎是从我有限的测试相当准确的，但它运行快得令人难以置信，我想阻止它下降到机器的实际时钟速度。
我当前测试循环是这样的：
// Just loop infinitely.
while (1 == 1)
{
CPU.ClockCyclesBeforeNext--;
if (CPU.ClockCyclesBeforeNext <= 0)
{
// Find out how many clock cycles this instruction will take
CPU.ClockCyclesBeforeNext = CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].CpuCycles;
// Run the instruction
CPU.ExecuteInstruction(CPU.Memory[CPU.PC]);
// Debugging Info
CPU.DumpDebug();
Console.WriteLine(CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength);
// Move to next instruction
CPU.PC += 1 + CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength;
}
}
正如你所知道的，每个操作码所花的时间来完成一个具体金额，所以我不跑下一个指令，直到我倒计数CPU时钟周期。 这提供了操作码之间适当的时机，它只是整个事情的方式运行快。
目标CPU速度是1.79mhz，但我想任何解决问题的时钟保持速度甚至为我增加了复杂性1.79mhz，所以我不必调整它。
有任何想法吗？
我很多年前写了一个Z80模拟器，并做周期精确的执行，我分了时钟速率成若干小块，不得不核心执行很多个时钟周期。 就我而言，我把它绑在游戏系统，我模仿的帧速率。 每个操作码知道多少次了执行，直到被执行指定的周期数的核心将继续运行操作码。 我有一个外循环运行，将运行CPU内核，运行仿真系统的其他部分，然后睡觉，直到下一次循环的开始时间。
编辑：添加例如运行循环。
int execute_run_loop( int cycles )
{
int n = 0;
while( n < cycles )
{
/* Returns number of cycles executed */
n += execute_next_opcode();
}
return n;
}
希望这可以帮助。
看看灵感原来的QuickTime文件。
这是很久以前写的，显示视频意味着刚换的时候依然在帧足够高的速度，但苹果的家伙决定他们需要一个全职的管理框架。 在第一次设计看起来过度设计，但让他们对付广泛不同的速度要求，并让他们紧密同步。
你是幸运的，6502具有确定性的时间特性，确切的时间每条指令需要的是有据可查的; 但它不是恒定的。 某些指令需要2个周期，其他3就像在QuickTime帧，视频没有参数“每秒帧数”，每帧告诉它要多久才能在屏幕上。
由于现代的CPU是如此的不确定性，和多任务操作系统的甚至可以几毫秒冻结（虚拟内存！），你应该保持一个标签，如果你落后于计划，或者如果你可以采取几微秒午睡。
正如肯尼迪说，要做到这一点最常见的方法是配合CPU的速度到（模拟）视频输出的垂直刷新 。
挑多个循环到每视频帧运行。 这通常是机器特有的，但你可以通过类似计算的话：
cycles = clock speed in Hz / required frames-per-second
然后，你还可以得到做一个休眠状态，直到视频更新被击中，在这一点上，你开始CPU仿真的下一个n个周期。
如果你模仿特别的东西，那么你只需要仰望的FPS速度和处理器速度得到这个近似直角。
编辑：如果你没有任何外部时序要求，那么这是正常的一个仿真程序只运行尽可能快所能。 有时候，这是一个预期的效果，有时不:)
我会用时钟周期来计算时间和他们睡觉的时间差。 当然，要做到这一点，你需要一个高分辨率的时钟。 他们的方式你正在做它要秒杀CPU中纺循环。
是的，因为大部分的时间之前说你不需要CPU仿真器在真实的东西相同的速度模拟指令。 什么用户感知的计算（即音频和视频输出）的输出 ，所以你只需要在同步与这样的输出这并不意味着你必须有一定的精确CPU仿真速度。
换句话说，如果视频输入的帧速率，让我们说，50赫兹，然后让CPU仿真运行速度，因为它可以在屏幕上画，但一定要输出的正确率（50赫兹）屏幕框。 从外部来看你的模拟器是在正确的速度模拟。
为了做个周期精确，即使在执行时间是一个多任务操作系统，如Windows或Linux的非有道理的，因为模拟器指令时间（tipically 1us的复古80年代的CPU）和现代操作系统的调度时隙具有可比性。
想输出的东西在50Hz的速度是一个简单的任务，你可以做任何现代的机器上很好
另一种选择是，如果可用的音频模拟实现，如果音频输出绑定到系统/ CPU时钟。 特别是我知道，这是与8位苹果] [电脑的情况。
一般声音在一个固定的大小（这是一个固定的时间）的缓冲器中产生，所以操作（产生数据等），这些缓冲器可以通过同步原语被捆绑到CPU的吞吐量。
我在做的东西多一点一般使用情况下为主，过程如时间转换为指令的估计量，反之亦然的能力。
